An invasive, distal component of an electrosurgical assembly intended to deliver electrosurgical current in a bipolar configuration (i.e., without a return electrode) to tissues for cutting/coagulation/ablation during endoscopic (including laparoscopic, arthroscopic) surgery. It is available in a variety of forms (e.g., exchangeable electrode for electrosurgical forceps, rigid electrode, flexible endoscopic probe) which may include a lumen for suction/irrigation. It does not include a handpiece or housing and has no electrical or mechanical controls (e.g., does not include ring-handles). This is a reusable device.
